I'm guessing that it has finished all tests - the crash actually occurs after Cypress prints out that it is running the last spec file.

I tried setting numTestsKeptInMemory to 0, and that did not help.

Desired behavior:

cypress run should not crash.

Steps to reproduce: (app code and test code)

Can't upload my repo, sorry.

Versions

Cypress package version: 3.1.4
Cypress binary version: 3.1.4

Mac OS X 10.13.6

[jennifer-shehane]

We will need a reproducible example of this crash behavior. Can anyone provide a way to reproduce this - app code + test code?

[gustawx]

I have the similar problem also when running all specs from cypress runner

There is another problem related to this. When i set up node flag:
export NODE_OPTIONS=--max-old-space-size=4096

cypress fails to run without any error! The process just closes. I'm not sure if this is a seperate issue so I don't open a new one...

the tests that I'm running are mostly API tests ( normal rest calls ) and 3 small UI tests. I think i can't post a code here but this is really nothing special, just some visit(), request() etc

EDIT:
the error above occurs before tests even start running

[kjellski]

We're facing the same issue, but are unable to share the code unfortunately.

[jennifer-shehane]

@gustawx Setting the NODE_OPTIONS environment variable if you have this set - as this causes Cypress to crash. This is due to an Electron bug prior to version 2.0.3, where having NODE_OPTIONS set causes either a failure or arguments to be ignored. electron/electron#12695 (comment)

To unset NODE_OPTIONS environment variable

MacOS / Linux

unset NODE_OPTIONS # this is not the same as export NODE_OPTIONS=

Windows

set NODE_OPTIONS=

We have open issues for this being fixed that you can follow here:

• NODE_OPTIONS should not exit 0: Do not exit with 0 when running with NODE_OPTIONS #1676
• Electron update: Upgrade to the latest version of Electron #3568
• Version 4.0 Release: Test finishing with commands in its queue when calling method on undefined with cy async return #284
  0

Unfortunately we have to close this issue as there is not enough information to reproduce the problem.

Please comment in this issue with a reproducible example and we will reopen the issue. 🙏
